Chronic Myeloid Leukemia (CML) is a cancer of hematopoietic stem cells that is caused by the oncogene BCR-ABL1. BCR-ABL1 encodes a constitutively active tyrosine kinase protein that leads to the uncontrolled proliferation of myeloid cells, which is a hallmark of CML. A current therapeutic approach for the treatment of CML, Tyrosine Kinase Inhibitors (TKIs), effectively inactivates BCR-ABL1 kinase activity; however, drug resistance to TKIs limits the long-term potential for this treatment. Proteolysis Targeting Chimera (PROTAC) has emerged as a promising pharmacological approach for degrading, rather than inhibiting, targeted proteins by harnessing the ubiquitin-proteosome system. This process involves tagging a Protein of Interest (POI) with ubiquitin by the E3 ubiquitin ligases, which subsequently target the protein for proteasomal degradation. The N-end rule or the N-degron concept describes the correlation between the metabolic stability of a protein and the biochemical identity of its N-terminal amino acid.

Breast cancer is divided into subtypes based on aggressive, genetic and stage. The precise cause of the problem is still unknown. However, the following significant risk factors have been found: sex, age, heredity, not having children, breastfeeding, elevated hormone levels, and personal lifestyle. The presence or lack of three nuclear receptors ER, PR, and HER2/ERBB2 (triple negative) and the amplification of the HER2/ErbB2 gene are the clinical criteria used to classify breast cancer. Chemotherapy is still the cornerstone of treatment for triple-negative breast cancer (TNBC), even. If, for the first two groups of patients,receptor-specific therapy is used.

Recent studies indicated that lncRNAs participate in various biological processes, such as chromatin remodeling, transcriptional and post-transcriptional regulation, and the modulation of cell proliferation, death, and differentiation, hence influencing gene expression and cellular function. ADAMTS9-AS1, an antisense long non-coding RNA situated on human chromosome 3p14.1, has garnered significant interest due to its pivotal involvement in the advancement and spread of diverse malignant tumors. ADAMTS9-AS1 functions as a competitive endogenous RNA (ceRNA) that interacts with multiple microRNAs (miRNAs) and plays a crucial role in regulating gene expression and cellular functions by modulating essential signaling pathways, including PI3K/AKT/mTOR, Wnt/β-catenin, and Ras/MAPK pathways.

Furthermore, it identifies ADAMTS9-AS1 as a potential early diagnostic biomarker and therapeutic target, offering novel opportunities for targeted intervention in oncology.</p>","PeriodicalId":7934,"journal":{"name":"Anti-cancer agents in medicinal chemistry","volume":" ","pages":"533-543"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142942992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
